A population's growth rate is strongly influenced by the proportions of individuals of particular ages . With knowledge of this age structure, population growth can be more accurately predicted. Age structure data allow the rate of growth (or decline) to be associated with a population's level of economic development.
What is meant by the age structure of population?

What are the three basic phases of population growth?
(i) The first stage is low population growth in an underdeveloped and technologically backward society. (ii) In second stage, birth rate and death rate being very high the net growth rate remains low. (iii) In third stage, birth and death rate are reduced hence, growth rate remains low in a developed society.
What are the 3 stages of population growth?
Stage 1: This is a state of high birth and death rates culminating in low population growth overall. Stage 2: With a consistently high birth rate and decreasing death rate, population growth surges. Stage 3: As the birth rate falls and the death rate remains low, the population continues to increase .
How can reduce population?
The solutions above all help to decrease poverty . In addition, lower child mortality through improved access to health care and better economic opportunities lead to smaller family size also. International aid, fair trade and global justice are all tools to help bring global population back to sustainable levels.
What is age structure and its importance?

How does rapid population growth affect the environment?
Populations and Environmental Issues
More people require more resources, which means that as the population increases, the Earth's resources deplete more rapidly . The result of this depletion is deforestation and loss of biodiversity as humans strip the Earth of resources to accommodate rising population numbers.
How is age structure determined?
Common summary measures of age structure include the mean age of population, median age of population, proportion of population at young ages (e.g., under age 20), and proportion of population at old ages (e.g., age 65 and above).
